What Is Lan Network?

A local area network, or LAN, is a network of connected computers in a room, building, or set of buildings. Local area networks have been around since the beginning of computer use. A LAN is defined as a user network whereby data is sent at high rates between people located relatively close to each other.
The Internet is a wide area network, or WAN, which is distinct from a LAN.  In contrast to the term Internet, local area networks are often called intranet, though sometimes this term refers to a cluster of LANs associated with a particular company or organization but not connected to the larger Internet. A local area network uses a hub or router to connect computers together.
